. residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Kinetoscope-Casings, of which the following is a specification, such as will enable those skilled. in the art to which it appertains to make and use the same.

This invention relates to kinetoscopes, being matter divided out of Letters Patent of the United States No. 1,0413% granted Oct. 15, 1912, and the object thereof is to provide a complete and, fireproof envelop or inclosure for the film and operative parts of the mechanism; a further object is to provide such an envelop, hereinafter referred to as a casing, which permits the ready removal of any or all of its sides, and two of the sides of which are hinged to give access to the kinetoscope mechanism; a further object is to provide a base plate having an approximately central wall which serves as the support for the said mechanism, thus leaving all the outer walls independent thereof; a further object is to connect the casing top with this central wall in order that the outer walls may be independent thereof and the kinetoscope be operative with all such walls removed, that is the kinetoscope mechanism; a further object is to provide a light-aperture and a fire-door therefor which effectually closes the same when the kinetoscope is not in operation; a further object is to provide film slits in the top and base of the said casing, adjacent the magazine and re wind drums, and also to provide means for effectually closing said slots whereby the film, if ignited, will not burn beyond said preventive means; and still further objects are to provide such casings which are simple in construction and assembling, which are formed of a plurality of parts whereby the cost of manufacture is reduced and repairs made very economically, which fully overcome the dangers heretofore experienced, and which are well adapted to the purposes for which they are intended.

My invention is'fullydescribed in the following specificatiomof which the accompanying drawings form a part, in which the separate p'arts are designated by the same .and in which reference characters in Figure 1 is a side elevation of a kinetoscope caslng constructed according to my inventlon; Fig. 2 is a section taken approximately on the line 2-2 of Fig. 1; Fig. 3 is 'a section taken approximately on the line 33 of Fig. 2; and Fig. 4 is a section taken approximately on the line 4-4 of Fig. 2.

In the drawings forming a part of this application I have shown a casing a, comprising a base a having a partition a approximately centrally thereof and extending entirely across the casing and over which is arranged the top plate a said base, partition, and top, being normally in permanent connection, and preferably in tegral with each other, and serve as the support for a rear wall a and a front wall 0,, the latter having two doors a and a hinged thereto, one on either side of the casing and, by reference to Fig. 1, it will be seen that the covering door a has a portion a divided therefrom and in ermanent connection with the base in any suitable manner and the purpose of which will be hereinafter explained, and it will be seen by the drawings that the base and top are provided with upwardly and downwardly directed lugs to receive screws or the like whereby the rear and front walls are held in position, the lugs being shown at a. The front wall a also carries a shutter casing b in the position of the shutter opening b of the-casing a, and the rear wall is preferably divided into a main portion a and an independent portion b provided, with the light aperture 6* and a fire-door b therefor, automatically operated as described in the patent above referred to, and suitable catches b are provided to lock the doors a and a to the rear wall a.

By reference to the drawings it will be seen that all the kinetoscope mechanism is carried by the partition 0. thus permitting the removal of the casing a without interfering with the operation of said mechanism, but the controlling and regulating devices of the said mechanism are all arranged exteriorly of said casing, vices comprising the operating crank (I held in the permanent portion a, of the casing, the trap-door push-button 0Z each of the views,

de-. I

the sprocket and shutter synchronizing lever at, the independent shutter adjustmg screw d, the lens-adjusting thumb-nut d, the stereo ticon focusing turn-button d and elevatlng button 0!, and it will be noted that all these devices are arranged in such position as to be readily and conveniently reached by the left' hand of the operator while his right hand is engaged turning the crank d and during the kinetoscope operation and without any interference therewith, the elements affected by the said devices, and the manner thereof, being clearly set forth in the above named patent, as also in other copending applications.

Secured to the top a is the magazinedrum 0 for the film 0 and secured to the base is the re-wind drum 0 slots 0" being provided whereby the said film may be quickly threaded, and adjacent each of these slots I provide a main roller c and two gravity rollers 0 slidable in inclined slots 0 the object of these rollers being to maintain a certain tension on the film, and to prevent the spread of fire to the said drums in the event of the film being ignited within the casing if the door is open, for there is no possibility of such ignltion if the door is closed for the reason that the casing it forms a hermetically closed envelop, the" only opening of which through which film ignition could occur bein closed when the film is motionless and being opened automatically when projection is desired and at which time the film is rapidly moved and in slight danger of ignition.

It will be observed that the rear wall a is provided with several convex projections, these serving to cover certain parts of the mechanism, but these projections are integral'with the wall and removable therewith, and from the foregoing it will be seen that the entire casing may be disassembled, with the exception of the parts a 6 without interfering in any way with the operation of the mechanism or removing any part thereof and, when in position, serves as a positive 'protection against fire or the introduction of foreign matter.

y mvention is very simple in construction and assembling, and entirely overcomes the dangers heretofore experienced in machines of this class and, while I have shown my casingdesigned for a specific type of kinetoscope, it will be obvious that I may adapt the same to other types and still be within the spirit of my invention, and with a reservation to myself of all suchchanges as may come within the scope of the following claims, what I claim as new, and desire to secure by Letters Patent, isp- 1. A kinetoscope, comprising a base, a vertical support thereon, operative kinetoscope mechanism carried by said support, a removable inclosing envelop for said mechanism ings in line with each other, one in the front wall provided with a shutter and one in therear wall provided with a closure, and automatic means for actuating said closure in the kinetoscope operation.

2. A kinetoscope, comprising a base, a vertical support thereon, a top, operative kinetoscope mechanism carried by said support and a removable inclosing envelop for said mechanism independent thereof comprising a front wall, a rear wall, and hinged side walls, said front and rear walls being provided, each, with an opening in line with each other, one of which is provided with an automatic closure and the other with a shutter, both operative with said mechanism.

3. A kinetoscope, comprising a base, a vertical support thereon, a top, operative kinetoscope mechanism carried by said support, a crank for operating said mechanism, and a removable inclosing envelopfor said mechanism consisting of front and rear walls independent of the said kinetoscope mechanism andprovided with openings therethrough in line with each other, and hinged side walls also independent of the said kinetoscope mechanism, a portion of one of said walls being in permanent connection'with said base to provide a support for said crank, whereby said inclosing envelop may be removed without removing said crank.

4. A kinetoscope comprising a base, a vertical support thereon, a top, operative kinetoscope mechanism carried by said support, and a removable inclosing envelop for said mechanism consisting of front and rear walls independent of the said kinetoscope mechanism provided with openings in line with each other, and side walls also independent of the said'kijletoscope mechanism hinged to said front wall, said base, plate, and top being integral and said front, rear and side walls being in' detachable engagement therewith.

5. A kinetoscope, comprising a base, a single vertical support secured to said base substantially centrally thereof, a top plate supported by said support, operative kinetoscope mechanism also supported by said support, and a removable mclosing envelop for said mechanism comprising two parts,

I cured to said-base, and said top plate, one

of said parts comprising a rear wall and the other comprising a front'wall, having two sidewalls hingedly connected thereto, and

v 5 means for detachably securing'the said side walls tosaid rear wall.

7. A kinetoscope comprising a base, a

vertical support thereon, a top, operative kinetoscope mechanism carried by said support, a crank for operating said mechanism and an inclosing envelopfor said mechanism, including front and rear walls inde-' pendent of said mechanism and provided with openings therethrough in line with each other, and side walls, one of which comprises a relatively small portion connected to said base-to provide a support for said crank and a relatively large hinged portion independent of the crank and the supporting means therefor, and adapted to be opened to permit access to said mechanism.

In testimony that I claim the foregoing as my'invention I have signed my name in presence of the subscribing witnesses this th day of July 1911.
